So-called Islamic State later claimed to be behind the attack, saying that Paddock had converted to Islam some months ago.

But the group provided no evidence for this and has made unsubstantiated claims in the past.

The FBI says it has made no connection between the attack and any international terrorist group.

A police statement said the shooting began at 22:08 local time on Sunday (05:08 GMT on Monday). Paddock came from the small town of Mesquite, some 60 miles (100 km) north-east of Las Vegas, and had resided in the hotel since 28 September.

Police in Mesquite have searched his premises and recovered a number of weapons. But they say he had not crossed paths with the police in the past.

Las Vegas police say the number of people injured now stands at 515.

Among those killed was an off-duty police officer.

Earlier, police announced they were seeking a woman, Marilou Danley, in connection with the shooting.

In his latest update, Sheriff Lombardo said she had now been located outside the United States and was not thought to have played any role.

Marilou Danley is believed to have lived with Paddock, and Sheriff Lombardo said he used some of her identity documents to check in to the hotel.
